BURNER-SUPPORT FOR GAS-RANGES.

Specification of Letters Patent.

Patented NOV. 21, 1916.

To all whom t may concern.'

Be it known that I, ALFRED B. BELL, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Burner-Supports for Gas-Ranges, of which the following is a specification. d

My invention relates to `burner supports for gas ranges and is an improvement on some of the features of construction shown in my patent burner boxes for gas ranges, Patent No. 1,159,351 grantedfNovember 9, 1915. In that lpatent is disclosed a pressed metal burner-box ink which the burners are' supported by a ytransverse bar or bars having downwardly turned ends removably inserted in vertical pockets formed in a lining member of the burner-box. In the patent also the burners are described as each having a tapered downwardly extending lug mo-unted in a corresponding hole in the burner supporting bar, the burner having supporting surfaces or lugs on each side of the tapered lug mounted in the hole, whereby the burners are located both horizontally and vertically when the same are mounted in position on the supporting bars.

In the present application I will describe and claim an improvement on the structure referred to, whereby not only is the burner given a positive support so that it will not rock, but also the mixing pipe leading to and carrying the burner may be moved sufficiently to the left or right to take care of any slight inaccuracies in assembling the parts. This is of advantage since to obtain the best results the mixing pipes of the burners should be maintained quite accurately in alinement with the nozzles on the manifoldy to which they are connected. I attain these results by supporting each burner on a transverse bar having a slot formed on one edge thereof to receive a lug extending downwardly from the bottom of the burner, the burner having a second lug extending downwardly in substantial contact with the opposite edge of the'burner supporting bar. The top of the bar is flat and the bottom of the burner in contact with the bar is planed flat so as to give a positive non-rocking support for the burner. The slots in which one of the lugs on each burner engage are somewhat wider than the lugs to permit the moving of any burner and its mixing pipe slightly to the left or right to establish the correct alinement of the mixing pipe and the nozzle on the manifold upon which it is mounted, while at the same time lengthwise movement of each mixing pipe, when its burner is seated in position, is prevented by the straddling of the supporting bar by the two lugs on the burner.

In order that a clearer understanding of my invention may be had, attention is hereby directed to the accompanying drawings forming part of this application and illustrating an embodiment of my invention.

In the drawings, Figure 1 represents a plan view of a burner-box with burners supported therein, Fig. 2 is an enlarged partial plan view showing the construction of a burner supporting bar and the engagement of a burner therewith, Fig. 3 is a vertical section on line 3-8 of F ig. 1 to the same scale as Fig. 2, and Fig. t is a partial enlarged vertical section on line 4 4 of Fig. 1.

Referring to the drawings, the burnerbox 1 is illustrated as being provided with a lining member 2, having vertical side walls 3, in which pockets 4t are formed by pressing the metal of the sides inwardly and slitting the metal horizontally above and below the pressed in portion to form integral straps.

The burner supporting bars `5 have downwardly bent ends (3 removably inserted in the pockets 4f. Preferably the horizontal portions of bars 5 are formed with downwardly extending rear flanges 7 The burner supporting bars 5 have slots 8, preferably square, cut in one edge thereof, this being the front edge when the vertical flange 7 of the bar is located at the rear as illustrated. The manifold or gas supply pipe 9' tom of the burner, these lugs being adapted to straddle the supporting bar 5 in the manner shown in Fig. ll, when the burner is mounted in position. As there illustrated, the lug 14 of each burner engages in the corresponding slot 8 of its support 5, the other lug 15 of each burner extending downwardly to the rear of flange 7 of the burner support, the distance between a pair of lugs 14 and 15 being only slightly greater than the distance between the rear edge of a slot 8 and the rear edge of the bar 5. The bottom of each burner which is adapted to con tact the top surface of a bar 5 is planed flat as illustrated at 16 in Fig. 3, so that the burners have positive non-rocking support on the bar. The slots S are of a somewhat greater dimension in the direction of the length of bar 5 than the width of lugs 14 so that when the burners have been mounted in position the same may be moved a short distance in the direction of the length of the burner support, to properly aline mixing devices 12 with the nozzles on the manifold in case of any slight inaccuracy in assembling of the parts. Such adjustment is, of course, not possible when the burners are provided with tapered lugs iitting closely in corresponding holes in the burner support.

Having now particularly described my in- Copies of this patent may be obtained for ve cents each, by addressing the vention, what I claim and desire to protect by Letters Patent is as follows:

1n a gas range, the combination of a burner support comprising a horizontal transversesupporting bar having a slot in one edge portion thereof, a manifold, a mixing pipe movably connected to the manifold, and a-burner carried by said mixing pipe, said burner havin@ a downwardly extending lug loosely engaging in said slot and a second downwardly extending lug adapted to loosely engage the opposite edge of said supporting bar when the first lug is in the slot, both the top surface of said bar and bottom surface of said burner in engagement therewith being flat and horizontal, said lugs being separated by a distance from front to rear slightly greater than the bearing width of a bar between a slot and the opposite edge of the bar, and said slot being of a slightly greater dimension lengthwise of the bar than the width of the lug seated therein, substantially as set forth.

rJ'Chis specification signed and witnessed this 25th day of February, 1915.
